Term for old folk sayings about the weather, usually formulated in rhyme, and the consequences for agriculture, usually drastically formulated as positive or negative. They are used to make predictions based on past experience. They have evolved over centuries through close observation of natural events and have been passed down from generation to generation. The predictions often refer to a so-called Lostag. Lostays (also Lurtage) are fixed days in the calendar which, according to old folk belief, allow predictions about the weather conditions of the following weeks, months and, more rarely, the coming year, determine the most favourable time for various agricultural activities (such as sowing or harvesting) and also allow forecasts about the expected harvest.
